- Description:
- This is a simple but nicely engraved vertical sundial about 2-foot square made of concrete. The hour lines are delineated every half hour and marked on the hour in Arabic numbers. The gnomon is at least 1-inch thick, now epoxied into place. The hour lines converge correctly to the morning and afternoon toe of the gnomon, but no split noon hour line is seen. The dial is slightly recessed into the brick wall on the eastern edge correcting the Joplin street lay out of 1873 that used magnetic north that was 10 degrees east of north.
